Patent DE-3731679-A1 (DE)
Title: Contactlessly controlled sanitary fitting
Inventor: GRUBER WALTER F
IPC: F16K31/40
Filed: 1987-09-21
Abstract: In a contactlessly controlled sanitary fitting, there is at least one sensor and this sensor can be used for the continuous adjustment of the rate at which the water flows out. For this purpose, use is made of a pilot-controlled valve, the actuating member of which is an electric stepping motor. The rotary motion of the electric stepping motor is converted by a mechanism into a linear motion of a tappet. The tappet in turn moves the closing element which closes or opens the pilot opening of a diaphragm. The diaphragm, for its part, controls the actual flow of water in conjunction with a valve seat. The overall arrangement of the valve is such that the diaphragm reliably follows the position of the closing element in all intermediate positions between the completely closed position and the completely open position. Continuous adjustment of the flow of water is thus possible with the minimum possible use of energy (Figure 4). <IMAGE>
Patent DE-3734672-A1 (DE)
Inventor: STRYBEL RICHARD V
IPC: B21D7/00
Filed: 1987-10-13
Abstract: A manual tube bender has a swivel connection of the handle 21 to the shoe 16 for facilitating repositioning of the handle in providing tube bends of greater than 90 DEG , while avoiding crossover of the shoe handle 21 with the handle 19 of the mandrel 11. The shoe handle 21 includes a cylindrical extension 28 which is rotatably received in a socket 34 in the shoe for rotation about axis 24 to enable the handle to be disposed in anyone of a plurality of preselected different dispositions. In use, shoe 16 is swung about the axis 13 of the mandrel 11 by movement of the handle 21 from a start position 16 through an angular distance A to approximately a 90 DEG  bend position. Handle 21 is then swivelled about axis 24, as indicated by arrow (2), to bring it back to adjacent the original start position whereupon further swinging of the shoe may be effected by movement of the handle over the distance B to a final position in which the tube T is bent 180 DEG  approximately. <IMAGE>

Patent DE-3739573-A1 (DE)
Title: Carex device
Inventor: HOLZ JOSEF
IPC: A61N5/06
Filed: 1987-11-23
Abstract: The carex device comprises a control console, the radiator heads on robot arms and connecting lines. The radiator heads are floodlight-like structures (known) which emit body-penetrating heat radiation (e.g. infrared radiation). One device always includes several radiator heads, preferably 4-8 heads for different therapies. The control console electronically controls the intensity and the diameter of the radiation cone, as well as the position and direction of the radiator heads. The device is used for treatment of cancer. It can be employed for the hyperthermia treatment and the DNA coagulation treatment. The device is very suitable for inoperable brain tumours. Its mode of operation: on treatment of a cancer patient the radiator heads are grouped via robots around the body and aligned such that the rays cross each other in an amplitude synchronous manner in the centre of the growth.   As a result, a much higher temperature is achieved in the centre than in the individual radiation paths where the temperature is not to exceed the normal temperature of 37@C by more than 3@C.

Patent DE-3741709-A1 (DE)
Title: Sawblade
Inventor: REHBEIN HARALD DR ING
IPC: B23D61/02
Filed: 1987-12-09
Abstract: A sawblade has a base body and non-straight-set teeth which are provided in recurring cycles and at different spacings in the cycle. The teeth are, at least in the region of their cutting edges, wider than the base body and are arranged in the cycle as follows: The number of teeth p in the cycle is even. The number of different spacings in the cycle corresponds to half the number of teeth p/2. Each cycle of length L contains two subcycles of half the length. Each subcycle (9, 10) has all the different spacings. The last spacing in the first subcycle (9) recurs as last spacing in the second subcycle (10). The further spacings of the first subcycle (9) are arranged in the order of their arrangement in the first subcycle in the second subcycle (10) at new places p-n, where n first runs through the odd numbers starting with 1 and then through the even numbers starting with 2 and the upper limit for n is formed by the largest odd or even number which is in each case smaller than p/2. <IMAGE>

Patent DE-3803338-A1 (DE)
Inventor: ARMOND JOSEPH A
IPC: B23Q3/15
Filed: 1988-02-04
Abstract: The chuck holding force is controlled by a dot-bar driver (78), (Fig 5) which, according to the level of a voltage applied thereio, causes various ones of resistors (86), (88), (98'') to be connected in the charging circuit of capacitor (103), (Fig. 4), in a phase control circuit which controls thyristors 56 and 58 via which current flows to the chuck 20. The holding force is indicated by LED's (178), (Fig. 7), controlled by a second dot-bar driver (176). In a VARIABLE mode, the voltage applied to driver (78), (176) can be set by a potentiometer (66). In a RELEASE (demagnetizing) mode the drive input voltage gradually decreases, causing a corresponding decrease in the chuck holding force, or the voltage on a capacitor (98) (Fig. 5) decays, and an oscillator (125), (Fig 4), causes thyristors 56, 58 to be triggered alternately thus periodically reversing the current direction in the chuck 20. The overall demagnetising cycle time and the current reversal period are independently adjustable by switches (158, (Fig. 7) and (153), (Fig. 4). A comparator 184 responsive to a chuck current sensor 182 is operable if FULL and VARIABLE modes to cause a relay 198 to stop operation of a grinder 12 if the chuck current is interrupted. If an improper mode is selected after the apparatus is set to the FULL or VARIABLE mode, a LOCKOUT signal is generated resulting in turn off of a transistor (208), (Fig. 7), effectively disabling all mode selection switches (62A) to (62D), and the capacitor (98) is also prevented from discharging so that the chuck current is held constant until the LOCKOUT signal is removed at which time only the RELEASE mode can be selected. <IMAGE>

Filed: 1988-02-15
Abstract: A description is given of a spinning machine with two spindles (9, 11), on each of which is provided a head (12, 22) with two spinning rollers (3, 4). The spinning machine has a U-shaped machine frame (8) with a changing device (17) built into it, the turntable (62) of which extends below both slides (18, 38) together with the spindles (9, 11). At the circumference of the turntable (62) there are feed and removal devices (24, 25, 34, 35) which ensure automatic operation of the spinning machine. The spacing of the rollers (3, 4) can be varied within a wide range during the spinning operation. With the method indicated it is possible to produce small workpieces with a widely varying diameter by the use of roller heads (12, 22) with spinning rollers (3, 4) that can be adjusted radially during operation. During spinning, the spinning rollers rotate about their own axis and revolve on the spindle (9, 11) around the fixed workpiece. On the turntable (62) of the changing device (17) there are holding devices (10-70) for the workpieces, into which the unworked workpieces can be inserted and secured against rotation by positive engagement. <IMAGE>

Title: Laser Doppler anemometer
Inventor: DAMP STEPHAN
IPC: G01P5/26
Filed: 1988-07-08
Abstract: The invention relates to a laser Doppler anemometer having a semiconductor laser, a collimating optics and a beam-splitting optics, in order to generate at least two partial beams from one laser beam. With the aid of a focussing device, the partial beams are projected into a measuring volume in such a way that they intersect inside the measuring volume. The essential point is that the focussing device consists of a number of beam-deflecting elements which is equal to or greater than the number of the partial laser beams and which are arranged in such a way that they deflect the partial laser beams emerging directly from the beam-splitting optics from the plane defined by the partial laser beams, with the result that they intersect in the measuring volume. The beam-deflecting elements can consist of simple totally reflecting mirror elements, with the result that an expensive focussing lense arrangement can be eliminated. In particular, the construction according to the invention permits a compact design of the overall arrangement.
Patent DE-3825634-A1 (DE)
Inventor: PIRCHER HANS DIPL ING DR
IPC: C21D8/02
Filed: 1988-07-28
Abstract: The invention relates to a process for the production of hot rolled strip or heavy plates from stainless and refractory steels or from forgeable alloys on a nickel basis with a final thickness in the range of 5 to 60 mm by the production of a slab from monobloc casting or by continuous casting and heating the slab at a temperature above 1100 DEG  C. followed by the hot rolling of the slab and accelerated cooling of the product rolled to the end thickness. The characterizing feature of the invention is that the heated slab is rolled without interruptions first to a maximum of 1/6 of its initial thickness, mainly by deformation passes in which the degree of deformation pass in the thickness direction is greater than the degrees of deformation shown by curve A in FIG. 1, in dependence on the surface temperature of the product. Then finish rolling is performed to the end thickness, mainly by deformation passes in which the degree of deformation per pass in the thickness direction is greater than the degrees of deformation shown by curve B1 or curve B2 in FIG. 1, in dependence on the surface temperature of the product and the pause between two adjacent passes as parameters. The surface temperature of the finish rolled product must be not less than 1030 DEG  C., if the product contains up to 1.0% molybdenum and not less than 1050 DEG  C., if the product contains more than 1.0% molybdenum. At the latest 100 seconds following finish rolling, the product is cooled at an accelerated rate with a speed in the core of more than 3 K/sec, more particularly more than 5 K/sec, to a temperature which is equal to or lower than 650 DEG  C.
